Task-oriented Framework for Communication-Efficient Federated Learning: From Isolated Optimization to Holistic Synergy
Fuqiang Pan, Yan Liu, Erwu Liu +1
Communication bottlenecks remain a primary obstacle to the large-scale deployment of federated learning (FL). This article proposes a comprehensive framework for building communica…
Integrated Positioning and Communications for PASS: A Robust Approach
Yaoyu Zhang, Xin Sun, Jun Wang +4
The pinching-antenna systems (PASS), which dynamically activate and relocate the pinching-antennas (PAs) along the dielectric waveguide, offer unprecedented potential for integrate…
Over-the-Air Computation via Segmented Waveguide-Enabled Pinching-Antenna Systems
Songnan Gu, Hao Jiang, Chongjun Ouyang +3
A segmented waveguide-enabled pinching-antenna system (SWAN)-assisted over-the-air computation (AirComp) framework is proposed. Three transmission architectures, namely segment sel…
Mutual Coupling-Aware Beamforming in Multi-User Continuous Aperture Array Systems
Junjie Ye, Zhaolin Wang, Yuanwei Liu +3
A mutual coupling-aware beamforming design for continuous aperture array (CAPA)-aided multi-user systems is investigated. First, a transmit coupling kernel is characterized to expl…
Multi-Mode Pinching-Antenna Systems: Mode Selection or Mode Combining?
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +1
This letter investigates multi-mode pinching antenna systems (PASS), where signals of multiple orthogonal modes can be transmitted within a dielectric waveguide and radiated by pin…
Sampling-Free Diffusion Transformers for Low-Complexity MIMO Channel Estimation
Zhixiong Chen, Hyundong Shin, Arumugam Nallanathan
Diffusion model-based channel estimators have shown impressive performance but suffer from high computational complexity because they rely on iterative reverse sampling. This paper…
